Factoring requires taking out a value out of the expression which result to an expression where the factors are shown. We factor the given expression above as follows:
<span>3y+30
3(3y/3 - 30/3)
3(y - 10)
When you distribute 3 into the parenthesis again you will still obtain the same initial expression. Hope this answers the question. Have a nice day.</span>
ANSWER
The length of

EXPLANATION
The object length given to us is,

The scale factor of the dilation is,

The image length can be calculated using the formula

We substitute the given values into the formula to get,

We multiply out to obtain,
Answer:
x = 8
Step-by-step explanation:
2(78°) = 20x - 4
156 = 20x - 4
add 4 to each side of the equation:
160 = 20x
divide both sides by 20:
x = 8
first make them into improper fractions 124/15 and 54/15 then subtract so it would be 70/15 then turn it into a mixed number 4 10/15
